March 6, 201016 yr Hi , I have a Beta Rev 3 250cc (2005 ).Recently I took the carb off to clean it (not an easy job ! ). When I have put it back together and started the bike it over revs,tried to turn the tick -over down with the two adjustment screws but it still over revs. Anybody know why my bike is doing this ?.Hopefully there is a simple solution but I don`t seem to be able to work it out myself. Your help would be much appreciated.
